another pump built from an old raptor

HClark · 10-14-2011, 01:16 PM

I said I wasn't going to do any more of these, and then got all carried away last spring anyhow. I really do think this will be the last one though. The pump rod is titanium, the forend pine, the grips hand checkered mammoth ivory, CO2 line copper, brass fittings, top bolt nylon, lower striker bolt is heat treated tool steel. Way too many hours, but it is one of a kind. Closed bolt Raptor pump gun number five for your viewing pleasure.

That copper tubing holds CO2?

I've thought about pumping my Illustrator, but just can't make the cut.

I'm thinking some countersunk flatheads would make a visible difference on the pump arm linkage. Idk why, but it seems like it would make a difference.

Why wouldn't copper hold CO2 ? The burst disc on the tank is copper, and much thinner than the wall of tubing is.

It would look nicer with flat head, but the wood is very thin, and I'm not sure it would hold up that way.

I think anodizing is gonna be my next new thing I learn about. It has dangerous chemicals & electricity, sounds like fun.

It's really nice for projects. But, there's something I like about uncolored aluminum and pine together.

I guess copper tube is a lot like macro line, different grades, and diameter always counts. I forgot that the last coil I had was some soft domestic water grade. Air conditioning tubing is in the right ballpark, but your burst disk might not go off first. You could use the same argument against the copper line, in that the burst disk is copper too, so which one will break first? I do like polished copper lines though.

Here's a good reference I just found...
